Premium Bonds - anyone ever win?

I have had £3,000 bonds for some time now and have neverwon anything, most winners seem to have at least £20,0000 or more worth in bonds. Is it worth having a small amount or do you know of any winners?

My gr5an did have £20,000 worth and she used to get £50 quite often. After she passed away my dad cashed them in and gave me, my sis and my mum £1000 each to buy bonds. Had them for 6 months and none of us have got anything.

I've won £50 before quite a few years back. Wouldn't know if I had now, because they're still in my mother's name (even though she's never brought me up and we don't like each other) and I don't know how to 'get hold' of them again
